Zinc Plating

Use of Zinc plating is rapidly increasing for rust protection and decorative applications, It is primarily due to rise in cost of Nickel metals & also, increasing restrictions towards using toxic Cadmium in desired applications. It can also provide more uniform thickness, does not tend to fill up holes or obliterate threads and conserves heating energy to a very great extent. Zinc is an ideal replacement for hot dip galvanizing where high precision is desired. Latest developments of Zinc alloy plating in conjugation of certain passivations provides extremely high corrosion resistance to the deposited coating which even surpass the service life of traditional Nickel Chrome deposits.

Cyanide Zinc

This is a widely used plating process but is facing a declined trend due to pressure on metal finishing industry to eliminate cyanide from all phases of production because of its toxicity and high cost of neutralization.

Zincbrite 610 Brightener

A highly concentrated brightener system designed to give excellent brightness at low as also high current densities. Suitable for vat and barrel applications and has very low consumption.

Acid Chloride Zinc

Chloride zinc process is very versatile and is another preferred option in fast replacing cyanide Zinc primarily due to relative ease of operation, higher plating speed, lower power consumption, instant visible brightness response, no cyanide neutralization costs.

Zinthobrite 978 Process

Very versatile chloride Zinc process. Produces extremely bright and levelled Zinc deposits both in rack and barrel plating systems. Highly tolerant to impurities like iron. Remarkable levelling and ductility properties. Zinthobrite 978 Process offer very good receptivity to all chromate conversion processes.

Zincalite 985

Acid Zinc brightener system with superb brightening ability. It permits operation even at higher temperature up-to 50°C. This product is specially formulated to offer low brightener consumption to the users & also, could be operated in all types of Electrolytes – only potassium chloride, mixed potassium & ammonium chloride & also, only ammonium chloride types.

Post Plating Passivation For Zinc

Chromate Conversion Coatings are applied to the metal surface to enhance corrosion resistance and paint adhesion. Additionally, chromating process brightens zinc and cadmium plated surface & hence, improves the aesthetics of the substrates. Conversion Coatings are normally applied by immersion or by spray.

Hexavalent chromate  Conversion Coating

Yellow : Ginthox 995

Produces bright, iridescent coating on chloride Zinc plated parts without use of nitric acid; high corrosion resistance and excellent for paint / organic finishes.

Olive Green : Zincafix 958

Single liquid concentrate produces a glossy olive green coating, suitable for Zinc deposits from all types of Zinc plating processes.

Black : Ginthox ZB 992 / Ravenox ZB 993

Jet-black chromate coating on Zinc plated parts.

Trivalent chromate  Conversion Coating

 Blue : Trichrome HB 1720

Trivalent chrome Passivation produces pleasing thick blue finish.
